is secured to a twisted wire core.and kan yobject of the invention, among others,- s the productiono-f a machine that. shall Abe simple in construction and particularly rapid and Otherwise eflicient in Operation. One form of machine embodyingmy injvention and in the construction `and use-of which the objects herein set` out, aswell as Others,may be attainedis illustrated inthe accompanying drawings, in which` Figure 1 isa viewifjsi machine embodying my invention,

Figure 2 is atop view of (my improved machine v y, i'

In the accompanying drawings lthe numeral 5 -indicates the bed of;in'y improved machine that may be Vsupportedin any de-y sired manner, as by legs 6, this machine, in

the specific form herein illustrated'and described, embodying mechanism for trimming;

thebrush material to a round `form in cross section, together with mechanism for afterwardsbending the trimmed structures into A a fornipreparatoryto receivingthe handles,

ing Vthe brushesto the trimmingmechanism and, therefrom to; .the bending mechanism, said trimming and bending mechanisms being connected to 'operate .in-unison sothat brush structures are simultaneously` deliversupply ofl said structures tof-the bending mechanism isA maintained sufficient to supply' the demand of said bending mechanism 'and `do no breakthe sequence of bendingoperations. 7 f

yThe bending and trimming,l mechanisms are .mounted upon the bed 5, the latter comyfprising. standards 7 secured to the bed and j ,rising c therefrom at f opposite sides thereof A and supporting the lower ends Sof sidegpartsv sideparts each, having a slot 9 within which" the twisted wirecores v10 of brushgstiuctures 8 of a trimmer feed, there gbeing two of these 11 aie located and along which they. travel to l the'trim'ming mechanism, the side parts v being inclined.sufficiently to.. cause ythe brushes to gravitate toward v said trimming mechanising Thetrimmer c omprisesa carle elevation of a rier composed of twoenddises12 each having notches to receive the ends of the brush cores, rsaid carrier being mounted in suitable bearings rotatably supported by the standards 7. vAratchet wheel 14 is secured vto the `bracket 19 rising from the bed5. VOne end of this lever is located in the path of movement of 4theend of a bending slide 20 comprising afportion of the .bending mechanism, saidnslide being operated for a complete reeipiocating movement tov and fro at Aeach bending operation.

A trimmer comprising trimming knives 21 supported by aV shaft 22 mounted in bearingslon standards 23 locatedIOnthe-'bed 5 is positioned underneath the path of travel of the brush structures 11 as theyV` are moved forward by the carrier herenbefore referred to, guides 211 being employed for Vdirecting movement ofthe brush structures and rfor preventingthe latter from falling out of the notches in thecari'ier. These structures are vso locatedand supportedby the guides'and carrier that they will freelyrotate, and as the rapidly rotating knives 21 come in contact with the peripheries` of the brush structures the latter are causedto rapidly rotate with aresult that trimming yoperation is effected in arapidand expeditious manner, brushl structures being trimmed smooth and true to the forni desired, this depending' Yupon ythe shape of the knives 21. The brush structuresherein shown` are of cylindrical f `"shape, but any other desiredshape, as rconical ,or otherwise, `may be imparted to said structure-S. i

As these brush structures pass from the action of the trin'nning mechanism they are moved'alon g a chuteor feed device comprising side parts 25 preferably of /\-shape, the

10o brush structures ,travelingy up on'e'cbranch of l which arms have Van oscillatory movement during the bending operation.

Briefly described the ends of the vbrush structures are delivered by the chute comprising the side lparts 25 in 'the path of movev ment "end of which is pivoted to a crank disc secured to a. shaft mounted in bearings in a housing 36, said shaft being connected as by bevel `gears with a driving shaft 37 j mounted on the housing 36 and having a driving pulley 38 secured thereto. The arms 28 are oscillated as by means of a rack89 secured to tlieslide 2() and with which rack the rody 34: is directly connected, the teeth of Vsaid rack meshing with pinions llO secured to the lower ends of shafts to the Lipper ends of which the bending arms 2S are attached.

The description thus far given is sufficient for the purpose of my invention embodied herein, the bending mechanism herein illustrated, as to the details thereof, being shown and, described in my copending application of Serial Number 756,861, filed December'l), 1924:, to which reference is hereby made for a. more ycomplete understanding` of the details of construction of said bending mechanisin, lif such shall be desired.

It will be noted that -the runway along which the brushes pass to the trimming mechanism and Vtherefrom to the bending mechanism comprises runners on each side ofthe machine, said runway being spaced apart intermediate `its ends to uprovide a y space for the carrier of the trimmingjmechanism, saidcarrier operatingto convey brush structures across the space between the parts of the runway. Y

In accordance with the provisions of the patent statutes l have described the principles of operation of my invention, together with the device which l now consider to represent the best embodiment thereof; but
